CWS Construction in Highland, CA | Square Deal Contractors
We provide independent CWS construction service across Highland, CA, covering CWS ProSeries siding, FireGuard roofing underlayment, DeckDefense ledger systems, and StoneHold retaining walls. What makes our work different here is straightforward: we know how Highland’s decomposed granite soils and Santa Ana wind exposure stress CWS products in ways valley-floor installers never see. That field knowledge means fewer callbacks and walls that stay plumb. Call (866) 623-7205 for a free estimate on any CWS repair, replacement, or new installation in Highland’s 92346 ZIP. As an independent contractor, we’re not tied to any manufacturer’s playbook, so our recommendations come from what actually holds up on Highland hillsides.
Why Highland Residents Choose Us for CWS Service
Highland sits in a strange construction pocket: flat enough to have mid-century ranch homes near Baseline, steep enough that any house off Greenspot Road might need engineered footings and retaining walls. That variety is exactly why we get called for CWS work. Our crews have installed and repaired CWS siding, roofing, and retaining systems across the foothill interface for years, including CWS repair in Muscoy, which means we’ve already learned what fails and why on this specific terrain. Nolan Breckett, our owner, grew up in the Baker Ranch area of Lake Forest and trained through Saddleback College’s construction technology program, where the framing and soils coursework still informs how he diagnoses the CWS failures we see in Highland. We stock OEM CWS fasteners, flashing, and underlayment accessories for critical weather and fire boundaries, and we spec quality aftermarket block or joist hangers only where they meet or exceed CWS load and fire ratings. That distinction matters on a hillside where a failed retaining wall means more than an ugly yard.

Common CWS Construction Problems We Solve in Highland
- ProSeries siding panel separation and fastener back-out. Highland’s hot inland summers put real thermal stress on south- and west-facing walls. Panels expand and contract daily, and over years the fasteners work loose, leaving gaps that invite embers and water. We see this constantly in the newer tract homes marching up toward the foothills. The fix is usually new OEM fasteners and re-seating the panels, but we check the underlying sheathing before we promise a simple repair.
- FireGuard underlayment wrinkling and edge lift at roof-to-wall junctions. Santa Ana winds drive embers hard against the roof line, and the underlayment at the eave and rake edges takes the worst of it. Wrinkling there isn’t cosmetic, it’s an ember trap. We re-flash and re-secure the edges, and in fire-interface zones we often add a layer of Class A protection before the finished roof goes back on.
- DeckDefense ledger corrosion and pull-out. This one is uniquely Highland. Decomposed granite holds moisture against galvanized hardware far longer than the sandy loam down in San Bernardino. We’ll find ledgers that look fine from ten feet away but have lost half their connector strength at the bolt holes. When load paths are compromised, it’s a replacement job, not a patch.
- StoneHold wall block shifting and bulging on steep foothill lots. The original walls we’ve repaired almost never had proper drainage. Rocky, variable soil permeability means water finds a path to the back of the block and then just sits there. Bulging follows within five to seven years. We rebuild with weep vents, drainage chimneys, and engineered footings sized for what’s actually under the wall.
- Mixed-material transitions failing where walls meet rooflines. Many Highland remodels added on to older ranch homes, and the joint between the old framing and the new CWS assemblies never got flashed correctly. We see this on additions up and down Crafton Avenue and the surrounding neighborhoods. Water gets in, and the CWS product gets blamed when the real issue is a transition detail that was never part of the original plan.
CWS Service in Highland: What Local Conditions Mean for Your Equipment
Highland’s lot-to-lot soil variability is the single biggest wildcard we deal with. Decomposed granite in one yard, rocky foothill loam in the next. A CWS foundation or retaining wall plan that assumes uniform valley soil from CWS in San Bernardino routinely fails inspection here, because the engineer’s assumptions simply don’t match what the excavator hits. We’ve learned to pull soil samples before finalizing any wall or addition plan, even when the city doesn’t require it. On a sloped lot off Ward Street, we replaced a failing CWS StoneHold retaining wall where the original backfill had no drainage against decomposed granite, causing the lower courses to bulge within five years. We installed new CWS block with weep vents and a gravel drainage chimney, then tied the wall to an engineered footing sized for the rocky soil we hit three feet down. The wall has stayed plumb through two wet seasons, and the homeowner passed county inspection on the first try. That’s the kind of site-specific work Highland demands, and it’s why we don’t treat a CWS wall here the same way we’d treat one on a flat lot in Redlands.
CWS Models & Products We Service in Highland
Our Highland crews work across all four major CWS product lines: ProSeries exterior siding, FireGuard Class A roofing underlayment, DeckDefense joist and ledger systems, and StoneHold retaining wall block. We use CWS OEM fasteners, flashing, and underlayment accessories for critical weather and fire boundaries, and we spec quality aftermarket block or joist hangers only where they meet or exceed CWS load and fire ratings. For most repair work, we keep common OEM flashing profiles, FireGuard rolls, and DeckDefense hangers stocked in our local inventory, which shortens turnaround for Highland clients who don’t want to wait on a distributor shipment. Full replacement projects, like a new FireGuard underlayment under a standing seam metal roof, get ordered to spec with lead times confirmed before we open the roof.

FAQs – CWS Construction in Highland
Yes, CWS FireGuard is rated for Class A fire-resistant roof assemblies and is appropriate for Highland homes in the fire interface zone, provided the edge detailing is installed correctly and the assembly is inspected as a system. The underlayment alone doesn’t make a roof fire-resistant; it has to be combined with the right covering and proper flashing at eaves, rakes, and roof-to-wall junctions. Given the Santa Ana exposure along the foothill edge, we recommend a full inspection before relying on an existing FireGuard installation. Call (866) 623-7205 and we’ll take a look.
West-facing walls in Highland take hours of direct afternoon sun, and ProSeries panels expand and contract significantly through daily thermal cycling. Over multiple seasons, the fasteners back out and panels separate at the seams. The standard fix is re-seating panels with OEM fasteners and adding proper expansion allowance at the joints, though we check the sheathing and WRB behind the siding before calling it a fastener issue. If the underlying layer is compromised, a panel re-seat alone won’t hold.
Decomposed granite drains unevenly and holds moisture against the back of the block, so we design every StoneHold wall with a drainage system, not just backfill. That means a gravel drainage chimney behind the wall, weep vents at the base, and an engineered footing sized for the actual soil we find, which often means site-specific engineering rather than a stock wall section. The walls that fail in Highland are almost always the ones that skipped drainage. We rebuild and replace with the water path as the first design constraint.
The main vulnerability in Highland isn’t the summer heat, it’s moisture held against the galvanized hardware by decomposed granite and the occasional winter rain event. We see DeckDefense ledgers with corrosion at bolt holes that looks far worse than the deck above suggests. When we find pull-out or section loss at the ledger, we replace with hardware that meets or exceeds CWS load and fire ratings, and we correct the drainage detail that caused the corrosion in the first place. A caulk patch won’t fix a compromised load path.
A CWS roof replacement in Highland typically runs $8,000 to $20,000 depending on roof size, slope, and whether the fire-interface exposure requires additional Class A assembly components. We schedule roof work around fire-season restrictions by coordinating with the local building department and planning tear-off and underlayment phases to avoid spark-producing work on high-wind days.
